We are investigating the photometric properties of Be/neutron star systems in the Magellanic Clouds using V, R, and I data from the MACHO and OGLE-II surveys. Here we give results for 6 systems, 4 of which are X-ray pulsars.

The long-term light curves for each of these systems were searched for periodic variations. We first pre-whitened the data by fitting an appropriate polynomial to “flatten” lengthy portions of the light curves. We then used the method described by Home & Baliunas (1986) to find periodicities in the relative magnitudes.
